STOVE.

Specification of Letters Patent Np. 31,751, dated March 19, 1861.

plane of section. Fig. 2, a horizontal section of the same, taken in theline y, 3 Fig. 1.

Similar letters of reference indicate corresponding parts in the twofigures.

To enable those skilled in the art to fully understand and construct myinvention, I will proceed to describe it.

A. represents a stove which may be of the ordinary cylinder or otherproper form, placed "on a hollow baseB, containing an ash-drawer C, asusual.

D, is. the draft or smoke pipe which projects from the upper part of thestove as shown in Fig. 1.

E, is a jacket which is of semi-cylindrical form fitted on the base B,and around the back part of the stove. This jacket is a section of acylinder which is larger in diameter than the stove A, and a space a, isconsequently allowed between the jacket and the back part of the stove.The jacket E. has a top plate 6, the inner end of which is in contactwith the stove A.

The space a, forms an air-heating chamber and it has a hot-airconducting pipe F, projecting from its upper end. The jacket E, extendsupward about two thirds the height of the stove, and the upper part ofthe stove A, is therefore exposed, the door 0, being in the exposed partof the stove.

The jacket E, may be of cast-iron and cast with the stove and the baseB, extends sufliciently far back of the body or cylinder of the stove toadmit of a register or "alve G, being inserted in it to regulate theadmission of cold-air into the lower part of the air-heating chamber a,the back plate of the base having holes cl, made in it, through whichholes the cold air passes, as shown by the red arrows in Fig. 1.

At the front part of the stove a perforated sheet-metal case H, isplaced. This case joints the jacket E, and forms with the latter aperfect cylinder around the lower part of the cylinder or body of thestove. The perforated case H, admits of heat being radiated from thestove and also admits of cold air passing into the air-heating chamhera. The case H, extends upward as high as the jacket E.

Theupper exposed part of the cylinder or body of the stove also radiatesheat within the apartment in which the stove is placed.

The lower part of the jacket E, has an opening or space 6, at its lowerpart. This opening or space may be provided with a cover or door toclose it when necessary. \Vhen a hot fire is required within the stoveand a considerable .quantity of heated air required to pass through pipeor conductor F, the space 6, should be open, when only a moderatequantity is required the cold air is admitted through the Valve orregister Gr, and in such quantities as may be required.

I do not claim broadly a stove or fire chamber encompassed by anair-heating chamber, for such device has been used; but,

Having thus described my invention, I claim and desire to secure byLetters Patent,

The construction of the jacket in two parts, one of which H isperforated so as to form a protector and radiating chamber while theother part E forms a hot air chamber, when the said parts are arrangedtogether and wlth the stove and air chamber,

and the whole is made in the manner herein shown and described.

M. B. STAFFORD.
